Anxiety and first time pregnancy.

Help!! I've suffered with anxiety for the last couple of years and was on propranolol (10mg). I stopped taking this regularly in December and found out yesterday that I'm a couple weeks pregnant. I know I can't go back on to propranolol, I was wondering if anyone has any helpful tips of how to deal with the anxiety in a heathy way, it's actually kept me off work today because I'm all over the place.
